c32969d036 sh: Do not use hyphen in exported variable name
arch/sh/Makefile defines and exports ld-bfd to be used by
arch/sh/boot/compressed/Makefile and arch/sh/boot/romimage/Makefile.
However some shells, including dash, will not pass through environment
variables whose name includes a hyphen.  Usually GNU make does not use
a shell to recurse, but if e.g. $(srctree) contains '~' it will use a
shell here.

Other instances of this problem were previously fixed by commits
2bfbe7881e "kbuild: Do not use hyphen in exported variable name"
and 82977af93a "sh: rename suffix-y to suffix_y".

Rename the variable to ld_bfd.

15a5ae3b09 kconfig: gconf: Fix Back button behavior
Clicking the Back button may navigate to a non-menu hierarchy level.

[Example]

  menu "menu1"

  config A
          bool "A"
          default y

  config B
          bool "B"
          depends on A
          default y

  menu "menu2"
          depends on B

  config C
          bool "C"
          default y

  endmenu

  endmenu

After being re-parented by menu_finalize(), the menu tree is structured
like follows:

  menu "menu1"
  \-- A
      \-- B
          \-- menu "menu2"
              \-- C

In Single view, visit "menu2" and click the Back button. It should go up
to "menu1" and show A, B and "menu2", but instead goes up to A and show
only B and "menu2". This is a bug in on_back_clicked().

a8f2b96ca9 PCI: pnv_php: Enable third attention indicator state
The PCIe specification allows three attention indicator states, on, off,

a2a2a6fc24 PCI: pnv_php: Fix surprise plug detection and recovery
The existing PowerNV hotplug code did not handle surprise plug events
correctly, leading to a complete failure of the hotplug system after device
removal and a required reboot to detect new devices.

This comes down to two issues:

 1) When a device is surprise removed, often the bridge upstream
    port will cause a PE freeze on the PHB.  If this freeze is not
    cleared, the MSI interrupts from the bridge hotplug notification
    logic will not be received by the kernel, stalling all plug events
    on all slots associated with the PE.

 2) When a device is removed from a slot, regardless of surprise or
    programmatic removal, the associated PHB/PE ls left frozen.
    If this freeze is not cleared via a fundamental reset, skiboot
    is unable to clear the freeze and cannot retrain / rescan the
    slot.  This also requires a reboot to clear the freeze and redetect
    the device in the slot.

Issue the appropriate unfreeze and rescan commands on hotplug events,
and don't oops on hotplug if pci_bus_to_OF_node() returns NULL.

1010b4c012 powerpc/eeh: Make EEH driver device hotplug safe
Multiple race conditions existed between the PCIe hotplug driver and the
EEH driver, leading to a variety of kernel oopses of the same general
nature:

<pcie device unplug>
<eeh driver trigger>
<hotplug removal trigger>
<pcie tree reconfiguration>
<eeh recovery next step>
<oops in EEH driver bus iteration loop>

A second class of oops is also seen when the underlying bus disappears
during device recovery.

Refactor the EEH module to be PCI rescan and remove safe.  Also clean
up a few minor formatting / readability issues.

80f9fc2362 PCI: pnv_php: Work around switches with broken presence detection
The Microsemi Switchtec PM8533 PFX 48xG3 [11f8:8533] PCIe switch system
was observed to incorrectly assert the Presence Detect Set bit in its
capabilities when tested on a Raptor Computing Systems Blackbird system,
resulting in the hot insert path never attempting a rescan of the bus
and any downstream devices not being re-detected.

Work around this by additionally checking whether the PCIe data link is
active or not when performing presence detection on downstream switches'
ports, similar to the pciehp_hpc.c driver.

4668619092 PCI: pnv_php: Clean up allocated IRQs on unplug
When the root of a nested PCIe bridge configuration is unplugged, the
pnv_php driver leaked the allocated IRQ resources for the child bridges'
hotplug event notifications, resulting in a panic.

Fix this by walking all child buses and deallocating all its IRQ resources
before calling pci_hp_remove_devices().

Also modify the lifetime of the workqueue at struct pnv_php_slot::wq so
that it is only destroyed in pnv_php_free_slot(), instead of
pnv_php_disable_irq(). This is required since pnv_php_disable_irq() will
now be called by workers triggered by hot unplug interrupts, so the
workqueue needs to stay allocated.

The abridged kernel panic that occurs without this patch is as follows:

b9f75396ec scripts: add zboot support to extract-vmlinux
Zboot compressed kernel images are used for arm64 kernels on various
distros.

extract-vmlinux fails with those kernels because the wrapped image is
another PE. While this could be a bit confusing, the tools primary
purpose of unwrapping and decompressing the contained kernel image
makes it the obvious place for this functionality.

Add a 'file' check in check_vmlinux() that detects a contained PE
image before trying readelf. Recent (FILES_39, Jun/2020) file
implementations output something like:

"Linux kernel ARM64 boot executable Image, little-endian, 4K pages"

Which is also a stronger statement than readelf provides so drop that
part of the comment. At the same time this means that kernel images
which don't appear to contain a compressed image will be returned
rather than reporting an error. Which matches the behavior for
existing ELF files.

The extracted PE image can then be inspected, or used as would any
other kernel PE.

4a5dcb3373 selftests/bpf: Fix test dynptr/test_dynptr_memset_xdp_chunks failure
For arm64 64K page size, the xdp data size was set to be more than 64K
in one of previous patches. This will cause failure for bpf_dynptr_memset().
Since the failure of bpf_dynptr_memset() is expected with 64K page size,
return success.

4c82768e41 selftests/bpf: Increase xdp data size for arm64 64K page size
With arm64 64K page size, the following 4 subtests failed:
  #97/25   dynptr/test_probe_read_user_dynptr:FAIL
  #97/26   dynptr/test_probe_read_kernel_dynptr:FAIL
  #97/27   dynptr/test_probe_read_user_str_dynptr:FAIL
  #97/28   dynptr/test_probe_read_kernel_str_dynptr:FAIL

These failures are due to function bpf_dynptr_check_off_len() in
include/linux/bpf.h where there is a test
  if (len > size || offset > size - len)
    return -E2BIG;
With 64K page size, the 'offset' is greater than 'size - len',
which caused the test failure.

For 64KB page size, this patch increased the xdp buffer size from 5000 to
90000. The above 4 test failures are fixed as 'size' value is increased.
But it introduced two new failures:
  #97/4    dynptr/test_dynptr_copy_xdp:FAIL
  #97/12   dynptr/test_dynptr_memset_xdp_chunks:FAIL

These two failures will be addressed in subsequent patches.

620e2392db net: dsa: microchip: Disable PTP function of KSZ8463
The PTP function of KSZ8463 is on by default.  However, its proprietary
way of storing timestamp directly in a reserved field inside the PTP
message header is not suitable for use with the current Linux PTP stack
implementation.  It is necessary to disable the PTP function to not
interfere the normal operation of the MAC.

Note the PTP driver for KSZ switches does not work for KSZ8463 and is not
activated for it.

84c47bfc5b net: dsa: microchip: Add KSZ8463 switch support to KSZ DSA driver
KSZ8463 switch is a 3-port switch based from KSZ8863.  Its major
difference from other KSZ SPI switches is its register access is not a
simple continual 8-bit transfer with automatic address increase but uses
a byte-enable mechanism specifying 8-bit, 16-bit, or 32-bit access.  Its
registers are also defined in 16-bit format because it shares a design
with a MAC controller using 16-bit access.  As a result some common
register accesses need to be re-arranged.

This patch adds the basic structure for using KSZ8463.  It cannot use the
same regmap table for other KSZ switches as it interprets the 16-bit
value as little-endian and its SPI commands are different.

KSZ8463 uses a byte-enable mechanism to specify 8-bit, 16-bit, and 32-bit
access.  The register is first shifted right by 2 then left by 4.  Extra
4 bits are added.  If the access is 8-bit one of the 4 bits is set.  If
the access is 16-bit two of the 4 bits are set.  If the access is 32-bit
all 4 bits are set.  The SPI command for read or write is then added.

Because of this register transformation separate SPI read and write
functions are provided for KSZ8463.

KSZ8463's internal PHYs use standard PHY register definitions so there is
no need to remap things.  However, the hardware has a bug that the high
word and low word of the PHY id are swapped.  In addition the port
registers are arranged differently so KSZ8463 has its own mapping for
port registers and PHY registers.  Therefore the PORT_CTRL_ADDR macro is
replaced with the get_port_addr helper function.

d1f3dbad6f selftests: drv-net: Wait for bkg socat to start
Currently, UDP exchange is prone to failure when cmd attempt to send data
while socat in bkg is not ready. Since, the behavior is probabilistic, this
can result in flakiness for XDP tests. While testing
test_xdp_native_tx_mb() on netdevsim, a failure rate of around 1% in 500
500 iterations was observed.

Use wait_port_listen() to ensure that the bkg socat is started and ready to
receive before cmd start sending. With proposed changes, a re-run of the
same test passed 100% of time.

to correctly move it when it will be needed to commonize other part of
the code.

Move *_aq_str() to new libie module (libie_adminq) and use it across
drivers. The functions are exactly the same in each driver. Some more
adminq helpers/functions can be moved to libie_adminq when needed.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  i40e: use libie_aq_str
  iavf: use libie_aq_str
  ice: use libie_aq_str
  libie: add adminq helper for converting err to str
  iavf: use libie adminq descriptors
  i40e: use libie adminq descriptors
  ixgbe: use libie adminq descriptors
  ice, libie: move generic adminq descriptors to lib
